1 0 all whom it may concern.-

Be it known thatI, JOHN F. OLEU, of the city, county, and State of NewYork, have invented certain new and useful Improvements in the Sabots ofProjectiles used in Ordnance; and I do hereby declare that the followingis a full, clear, and exact description thereof, which will enableothers skilled in the art to make and use the same, reference being hadto the accompanying drawings, forming a part of this specification, inwhich- Figure l is a central longitudinal section of a sabot attached toa projectile. Fig. 2 is a transverse section of the same. Fig. 3 is aperspective view of one of the metal supporting-pieces which is appliedto the sabot for the purpose of transmitting to the projectile the forceproduced by the explosion of the charge of the gun.

Similar letters of reference indicate like parts.

This invention consists, first, in a novel construction of the sabot ofa projectile used in ordnance, whereby it is attached to the pro jectilewithout the use of straps, and is caused to serve as an expandingpacking for the more effectual prevention of ,windage between theprojectile and the bore of the piece of ordnance from which it isprojected.

It consists, secondly, in fitting the sabot, which is made of wood orother comparativelyyielding material, with metal supportingpieces, soapplied to act upon shoulders pr0- vided upon the projectile as totransmit to the projectile in a positive and unyielding manner the forceevolved by the explosion of the projecting charge of gunpowder.

The drawings represent my improved sabot applied to a projectile, ,A, ofpeculiar form, which I term the fislrshaped projectile; but itsapplication is not confined to this kind of projectile, as it may beused with any proj ectiles which diminish in size toward the rear. Thebody of the sabot is composed of two or more pieces of wood, B B, (tworepresentech) arranged side by side lengthwise of the sabot, so thatthey combine to produce a cylindrical exterior, and held together by ametal band, 0, surrounding their rear ends. The cylindrical exteriorthus produced is of a diameter to fit easily to the bore of the gun. Thesaid pieces are hollowed out in front to produce an internal cavity, a,of a form to fit the extetheir rear ends, allows their front ends to besprung out slightly when the rear portion of the projectile is pushedtightly into the cavity a, but causes them to produce an elasticpressure upon the said portion of the projectile sufficient to retainthe sabot upon the projectile without the use of straps.

D d D (Z are the metal supporting-pieces, of which there are tworepresented, but of which there might be a greater number when the sabotis made of more than two pieces, B B. These supporting-pieces may bemade of iron, and are of the angular form shown in Figs. 1 and 2. Theportion D of each is received within the body of the sabot, and theportion (2 fits closely against or is sunk flush into the heel thereofand secured thereto by screws 6 e.

The front ends of the portions Dent er the cavity a at suitable pointsto bear against the shoulders f, which are formed upon the exterior ofthe projectile for the purpose, when the sabot is pressed hard forwardupon the proj ectile, and they are inserted into. narrow deep groovescut lengthwise in the inner faces of the pieces B B, of which the bodyof the sabot is composed, each being received half in one and a half inanother of the said pieces, as shown in Fig. 2; but the portions (1 dare of only half the width of the said portions D I), as shown in Figs.2 and 3, that each may be attached to one of the pieces B B by thescrews 6 e, as shown in Fig. 2, and permit the said pieces with thesupporting-pieces separately attached to be put together easily beforethe band C is put on. The putting on of the band (1 secures the twopieces B B together, and when they are thus secured thesupporting-pieces do not interfere with the expansion of the sabothereinbefore mentioned. The portions D D of the supporting-piecesfitting closely within the body are stiffened and prevented from bendingor buckling, and so caused to transmit to the projectile in anunyielding manner the.

force evolved by the explosion of the projecting charge 2t]1(l1)16"611l1the crushing up of the body B B of the sabot. The portion D of each one,owing to its greater width,- is partly supported by the portion (Z ofthe other.

To secure the band 0 in place, it may have an internal screw-thread, toscrew onto the elastic pressure, substantially as herein specipieces BB. fied, Without the aid of straps.
